Biodegradation Overview
Upon discovering that a bacterium, Pseudomonas putida, has the ability to degrade naphthalene through a specialized pathway, we worked on a proposed construct that serves as a thought experiment on the ability of C. elegans to acquire biodegradation capability. The P. putida ''pathway'' is extensive, however, we propose that with enough time and resources, the entire pathway could be engineered in C. elegans to allow the worm to eat up naphthalene.
Targeted Biodegradation: Naphthalene
In this project, we decided to focus on the biodegradation of Naphthalene. Naphthalene is an environmental contaminant that can be formed in industrial processes. Naphthalene is a polyaromatic hydrocarbon (PAH) and is considered to be a potential carcinogen. This chemical is a good target for bioremediation and can be broken down by the NAH7 operon of the P. putida bacteria.
NahD Enzyme
We put one of the enzymes of this pathway into the standard BioBrick format. While the enzyme (NAHD) that is encoded will not degrade naphthalene on it's own, in future applications a combination of the remaining enzymes has the potential to offer C. elegans full degradation of naphthalene.
